Every day the vets do their daily rounds treating animals around the zoo. The trouble is, the animals all hate the vets and hide whenever they visit. As head vet Ghislaine spends the entire day trying to lure the tortoises out from under a bush, Christa attempts to examine a penguin's ankle and Jo tires to treat a capybara - it's clear they are very unpopular. Silverback gorilla Jurgen spots an opportunity to use his 'popularity' and become the zoo's doctor. He is convinced Dr Jurgen's clinic will be more popular than the vets, but can he convince anyone to be treated by him instead?
